| vortex (vôr'těks') Pronunciation Key
Plural vortexes or vortices (vôr'tĭ-sēz') A circular, spiral, or helical motion in a fluid (such as a gas) or the fluid in such a motion. A vortex often forms around areas of low pressure and attracts the fluid (and the objects moving within it) toward its center. Tornados are examples of vortexes; vortexes that form around flying objects are a source of turbulence and drag. See also eddy. |
